Solar Energy is the energy that has been captured from the Sun and converted into useful electric current by using a variety of ever-changing technologies including photovoltaic, solar heating, photothermal, solar thermal power, solar photovoltaic, solar thermal power, and artificial photosynthetic power plants. Solar Energy is also known as the sun’s free energy. Solar Energy is one of the key renewable energies because it does not pollute the environment or cause any damage to the world in return for its production. The primary benefits of Solar Energy include:
The sunlight provides an endless source of clean, inexhaustible energy that can be harnessed and converted into electricity or fuel. Solar panels harness this solar energy and convert it directly into electric current. Solar panels are a crucial technology needed in order to use Solar Energy to produce electricity and heat in our homes. Solar radiation is captured by Solar Panels and transformed directly into electrical energy. The panels in turn heat up water to use as a supply for running our homes.
Heat is also a form of solar energy. Most people use it to heat their homes. This process is called convection and happens when the warm air near the surface of the earth is replaced by cooler air higher up in the atmosphere. When the hot water is produced by the heater, it takes heat from the lower temperatures and returns it to the warmer surfaces of the house, thereby creating a circulation of hot water within the house. This heating process is called convection and can be an effective means to produce electricity for heating a home, for example in conjunction with an existing boiler.
Photovoltaic cells on the other hand are used to collect the sunlight and transform it directly into electric current. It uses semiconductor material to absorb sunlight and in the process creates an electric potential which is later converted directly into direct current. These days, however, we need to have our electricity generated by using clean methods that do not damage the environment. Solar energy is a great example of clean energy because the sun is constantly shining into space, meaning it does not have to pollute the air. By using photovoltaic cells we are able to harness this free resource of sunlight and convert it into electricity for all kinds of uses.
One of the most popular and common photovoltaic cell types used to power solar systems today are those made from silicon. These devices convert light into electricity with the help of different chemicals that are found in silicon. There are also other silicon-based materials such as cadmium and iron that are used but these too require rare earth metals to make them effective. Other types of solar-powered devices that you may encounter include those made from gas or polymer materials.
If we continue to use fossil fuels and burn them they will significantly damage the environment. There is no doubt in my mind that we need to find alternative methods of generating energy. We need to reduce our dependence on fossil fuels and move toward renewable and clean sources of energy such as the sun. This is the only way we will be able to fully use the energy provided by the sun and protect our Earth from further deterioration. Solar energy is a key player in our fight to preserve the health of our planet.
